These WWI pattern RN Binoculars & HETHER LANTERN continued in service into the 1970s.

This pair is fitted with an 'Improved' Hether Lantern, Mk2, Patt. 16466, introduced in service in the Royal Navy in the 1950s.

The Hether Lantern was designed for use during night operations when ships were 'darkened' and showing no lights. The design of the barrel meant that the flashing light could not be seen peripherally and only if the reader was looking straight on.
